Jimi Hendrix’s brother Leon always claimed that the song was about their family – Jimi had told him so – but most people seem happier with the broader interpretation of the song as a meditation on the impermanence of all things, both good and bad.
Whatever the truth may be – and as with all art, isn’t the truth that works for you sufficient? – “Castles Made of Sand” was the second track on the second side of the Jimi Hendrix Experience’s second album. It was never released as a single, although it did become one of Hendrix’ more popular songs, and the album it was from “Axis: Bold as Love”, was ranked at 82 on Rolling Stone Magazine’s 500 Greatest Albums of All Time list in 2003.
